Our germanium lenses have a high refractive index—the highest refractive index amongst available IR transmitters. In addition, it reveals small chromatic aberration because of reduced dispersion.
It's got exceptional properties of transmission and Index of Refraction from the infrared spectrum which suits it for infrared optics. Even though our eyes are unable to see through Germanium, infrared radiation (In particular eight-14 um) is extremely transmissive by means of it.

The end aim is to make germanium optics that meet or exceed the demanding prerequisites of varied purposes, from infrared thermal imaging and sensing to spectroscopy and laser methods.
Specialized measurement and inspection: Working with specialized measurement applications and inspection gear, we make sure the floor roughness, curvature, as well as other critical parameters meet up with strict tolerances and excellent specifications.
There are various technical problems in production germanium parts for infrared optical devices, for instance keeping significant optical high-quality over a variety of temperatures, reducing unwelcome radial resistivity gradients, and lessening the absorption of infrared radiation.
Germanium ends up in some interesting spots together with protection aircraft navigation, reconnaissance and surveillance methods soaring during the stratosphere on an airplane or at the same time as Section of a satellite.
Germanium and germanium oxide have a very significant refractive index, this means that for a few window apps anti-reflective coating is needed.
At Lattice Components, we custom manufacture germanium lenses that has a effectively-defined and controlled system making sure that they satisfy stringent performance necessities:
Those people are rookie numbers and in most applications we’ll have to have to spice up our window alerts through several coatings. Whilst this may be a downside for optical Home windows click here this assets comes in handy for novel lens models and ATR optics where refraction is wanted.
